Note: Please note that builds will default to plain icons, these may not be as accurate. We apologize for the inconvenience.

Maybe it never coalesced into something brilliant. Maybe it never made it off the ground floor. Maybe we based our better ideas off of it. Basic builds are anywhere from downright bad to just shy of being good enough to showcase. These builds share the widest ratings and can lead to wildly differing levels of success.

Designed for:


This is a powerful Burst build. Take advantage of the perma stability provided by the Flamethrower.

  • Air Blast Flame Blast Switch to Rifle Over Charged Shot (you will not be knocked back because of the stability) Net Shot Jump Shot Blunderbuss
  • Use Elixir S if you need that hard stomp or need to get away.
  • Be the first to stomp your enemies. Your perma stability and on demand blind makes you a perfect choice for first hand stomping.
  • Drink Elixir B and Toss Elixir H whenever possible for the extra might. You need it for the dps.
  • Make sure to pick up med kits to heal up.
  • Mortar kit provides plenty of fields and utility. You can use Poison Gas Shell on downed enemies to slow down a res. You can drop an Ice Field or water field to blast an Ice aura or some healing. You can drop a Blind field to create an anti melee field.


  • Heavy CC and focus fire. This build can make you very arrogant to CC because of free stability. However, it is only one stack of stability. Another class can easily take away your stability by using more than 2 CC between 3 seconds and can leave you very vulnerable. Use Elixir B to stay alive.
  • Heavy Conditions- Engineers are generally weak to condis. However, there are a ton of condi removal, thanks to elixirs.

Juggernaut's a really interesting trait. It promotes sitting in flamethrower to get long-lasting might and stability, which is very strong, but the damage from Flamethrower is still low, save for the 2 skill. I think Flamethrower kit on its own is worth taking occasionally as the 2-5 skills are fine, but sitting in it for Juggernaut feels like a deceptive trap.

+ Between protection injection, random Elixir H protection, and the pulsing blind field from Mortar Kit 4, the build is deceptively tanky.

+ On-demand stability.

- Still squishy though and vulnerable to focus, especially with only Elixir S as a temporary breather skill. I'm really not fond of Backpack Regen as a trait for glass cannon, as healing traits like those have low value in low toughness/healing power builds whose goals isn't to win long fights.

- The damage output is good, but not any better than grenades/tool kit. Sure, you have more might stacks, but in exchange for those stacks, you're using (and possibly sitting in) the flamethrower kit. In exchange, you lose out on solid traits and utilities. On-demand stability is very good, but it isn't permanent unless you swap to flamethrower kit constantly on the 3rd second, and isn't worth the loss of all of the utility Tool Kit and damage grenade kit and explosives line offer.

I'll revisit the build after the balance patch which will buff Flamethrower's damage, but I have low expectations.

My issues with this build are similar to hanz

  • Marauder is not ideal for this build, firearms improves soldier/cele amulets more & in my opinion juggernaut works best when a bit tankier

  • Elixir X + healing turret would improve it substantially

  • I think the best similar builds are well covered on with or if intent on marauder,

    There's a thing about youtubers that people tend to forget: they are entertainers who often make special snowflake builds for the sake of standing out to gain viewers. This isn't necessarily the worst build ever, but both Marauder Rifle and Soldier Elixir are far superior. Way too squishy without Tool kit and vamp runes (or the Elixir S trait proc).

    Also I've heard that in Somalia you can get up to 8 years in jail for not taking Healing Turret and Explosives.

    And not taking Elixir X in a Marauder Elixir build... wow.

    Love this build. The burst is great and the combo is easy to set up. When I feel like I need to do more damage I pull out the mortar kit for the conditions, then use elixer b to start the combo.

    Very efective build. I have been running a slight variation with healing turret, skilled marksman and stimulant supplier trait for rotation speed and additional crit chance. I also experimented with rune of lyssa for its condi conversion... I have seen that it can trigger when swapping out of elite mortar kit. Rotation is very straightforward, easy to remember and allows you to change it up mid-fight if required.

    As PvP build I rate this good, as PvE it works super for me. If someone is starting enginner PvP I recomend this build, but Granade build is still supirrior in PvP.

    I use a variant of this Power FT build. As-is, this version is Good, but not Great as it suffers from conditions more than variants that pack Elixir Gun or Toss Elixir C. Nevertheless, this is a simple, solid offensive variant with significant burst and CC chain potential (Stability Rifle 4 into FT 3 is an absolute joy) against teams that lack heavy condition damage.
